Production-mode simulation with NEMO, ICON-ESM, ECMWF, EC-Earth, IPSL model - Milestone MS2

We have documented the current progress during the implementation of the production mode simulations on supercomputers of the consortium in deliverable D1.1 (https://zenodo.org/record/5795991) which is submitted together with this Milestone document. The model development teams are making good progress when preparing the model configurations for the pre-exacscale EuroHPC systems. We now hope to be able to get access to those machines soon, to make the final scalability tests in 2022.
